JS获取地址栏参数

    $(document).ready(function () {
        var locurl = location.href;
        var start = locurl.indexOf("?");
        var end = locurl.length;
        var tempstr = locurl.substring(start + 1, end)
        var temp = tempstr.split("=");
        var parm = temp[1] - 1;
        $(".ny_leftc_ul ul li").eq(parm).find("a").addClass("newtxz");
    });
